ISS microgravity drives unique phage–bacteria mutations, yielding improved therapeutic viruses

Experiments aboard the International Space Station reveal bacteriophages and their E. coli hosts acquire mutation patterns in microgravity that differ from Earth-based evolution. Some space-evolved phage variants demonstrated enhanced ability to infect and kill bacteria, and were used to generate improved therapeutic viruses targeting drug‑resistant infections.

Briefing

What Hype is tracking

  • Findings confirm that microgravity reshapes phage–bacteria coevolution, producing evolutionary pathways not observed on Earth and creating direct implications for crew microbiome management and spacecraft biosecurity planning.
  • Space-evolved phages produced measurable gains in infectivity and bactericidal activity and were converted into candidate therapeutics against drug‑resistant bacteria, underlining growing commercial microgravity R&D opportunities and on‑orbit biomanufacturing potential.
